Question

Think about the structure of the Hotel Krypton to help you in the process. Level 1 has two electrons in its s subshell. Level 2 has two electrons in its s subshell and six electrons in its p subshell.

Don't forget, subshell 4s should be listed before subshell 3d because electrons will fill the 4s room first. Remember the total number of electrons must add to 36.

Answer 1

Could you provide a screen shot that would help me answer your question better.

Answer 2

1s2 2s2 2p6 4s2 3d10 4p6

1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6

1s2 2s2 2p6 3s2 3p12 4s3 3d5 4p6

spaced them out to make them easier to read.

Answer 3

we want the electron configuration for Krypton.

this diagram shows how the periodic table is divided into s, p, d, f blocks. Each s block subshell has 2 electrons, each p has 6, each d has 10 (don't need to know it for this problem but f block subshell has 14 electrons)

now, we look at a regular periodic table (ptable.com has one). we count electrons starting all the way up from 1s until we have 36 electrons.

1s is the first s block. it has 2 electrons, so we write 1s2.

2s2 is next.

then the 2p blocks. remember, p subshell has 6 electrons, so we write 2p6.

keep going until you're at Krypton.
